use the rule of distributive property. 
a × (b + c) = (a × b) + (a × c)

-7(4x - 3)

-28x + 21

hope this helps, God bless!

In order to find the equivalent expression, we can use the distributive property of multiplication over subtraction.

-7 × 4x - (-7) × 3

- 28x - (-21)

- 28x + 21

The equivalent expression is

C) -28x + 21
